TOOL-HEATING DEVICE.

SPECIFICATION forming part of Letters Patent No. 233,801, dated October 26, 1880.

Application filed August 2, 1880. (No model.)

To all whom it may concern:

Be it known that we, EDWARD B. POWERS and JAMES H. STEVENS, both of Weymouth, in the county of Norfolk and Commonwealth of Massachusetts, have invented an Improved Tool-Heating Device, of which the following is a specification.

This invention has for its object the followingdescribed improvement in tool-heatingde.

vices, reference being had to the accompanying drawings, forming a part of this specification, in explaining its-nature, in which- Figure 1 is a front elevation of one form of our invention; Fig. 2, a vertical section on the line 00 00 of Fig. 1 Fig. 3, a vertical section of a modification in construction; Fig. 4, a plan of modification, and Fig. 5 a vertical section thereof on the line y y of Fig. 4.

The invention herein described is adapted for use in heating hand and other tools employed by boot and shoe makers, such as edgesetters or burnishers, sole-burnishers, shankburnishers, stitch-wheels, 850.; but the principle may be employed also for heating any other class of tools.

It consists in means, hereinafter described, whereby the tool is supported and keptin contact with a heating medium.

In the drawings, A represents a metallic shell, preferably of cast-iron, containing the chamber a, which may be arranged to extend horizontally therein from the side surface, as represented, and may be of a varying height or width, to accommodate tools of varying thicknesses or sizes; or the chamber may be extended downwardly from the upper surface of the shell, or otherwise arranged therein. The walls of this chamber preferably are heated by hot air, steam, water, or other heating medium introduced into the interior of the shell through the passage 1), while the exhaust passage or passages I) maintain a proper circulation.

The heating chamber or bed is provided with one or more automatic yielding pressureplates, whereby the tool may be held against the heating-surface with sufficient firmness to prevent its displacement by the jar of the bench supporting the heater or that of the room, or caused by the operatorin placing and removing other tools, and whereby, also, the tool is more quickly and uniformly heated by being kept in contact with the heating bed or plate, and for this purpose we represent in Figs. 1, 2, 4, and 5 the spring presser-plates O, which are fastened to the shell by screws 0, and which may be provided with the slots 0,

by which their position in relation to the heating bed, plate, or surface may be adjusted either by moving the plates toward or from the bed, as described.

The spring presser-plates may have the form and bear the relation to the heating bed or plate shown in Figs. 1 and 2, or that shown in Figs. 4 and 5, or may be of any other shape, and may occupy any other position in relation to the heating bed or plate to properly hold and maintain the tool against it. The presserplate may be also a spring, as shown, or it may be used in connection with an independent spring, or it may be attached to a weighted lever, whereby it is held in a given position in relation to the heating bed or plate when not in use, and automatically yields when a tool is inserted between it and the heating-bed, and automatically returns to its yielding position when the tool is removed. As an equivalent for the yieldin g presser-plate, we showin Fig. 3 a shell made in two parts hinged together, and having the heating-chamber for holding the tools between them. This construction provides for a yielding movement of one heatingplate in relation to the other, and ifthe Weight of theupper part is not sufficient to provide suitable pressure for holding the tool the two parts may be held together by spring-pressure. Any other equivalent for the construction herein described for giving the presser-plate an automatic yielding movement in relation to the heating bed or plate may beused.

The advantages of this invention are obvious.

We are aware that Letters Patent No. 100,017, granted J. M. De Lacy, for steam heater, dated February 22, 1870, describes a steamheating device consisting of a box provided with recesses for the reception of the tool, and inlet and outlet passages; and that Letters Patent No. 200,875, granted Fayette S. Robinson, for improvement in soldering apparatus, dated March 5, 1878, describes an apparatus in which the soldering-iron is heated by means of the flame of a lamp or a gas-jet, and which contains certain appliances for holding the iron while it is being heated, consisting of two supporting-plates, between which the iron is thrust; and that Letters Patent No. 222,859, granted W. S. Boyd, 3d, dated December 23, 1879, describes an improvement in tinners fire-pots, consisting of various devices whereby a soldering-iron is supported in the flame of an oil-lamp; but as the said patents do not describe a heating device consisting of a metallic shell having one or more heating beds 01 plates which form a part of the wall of the shell, and which are adapted to be heated by steam or otherlike heating medium introduced within the shell, and a yielding pressure-plate for holding the tool in contact with said heated bed or plate, we do not consider that any of them embrace the spirit of our invention.

Having thus fully described our invention, we claim and desire to secure by Letters Patent of the United States- 1. In a tool-heating device, the combination of a metallic shell, A, having one or more heating plates or beds, a, forming part of the shell,

adapted to be heated by steam or other like medium introduced therein, with one or more yielding pressure-plates bearing a position in relation to the heating plate or bed described, and adapted to hold the tool thereto, substantially as and for the purposes set forth.

2. In a tool-heating device, the combination of a metallic shell, A, having one or more beds or plates, a, forming a part of the shell, and adapted to be heated by steam or other like heating medium introduced therein, with a yielding pressure-plate adapted to be adjusted to and from said bed or plate, substantially as and for the purposes described.

3. In a tool-heating device consisting of a metallic shell, A, having one or more beds or plates, a, forming a part of the shell, and adapted to be heated by steam or other heating medium of a like nature, a yielding pressure-plate for holding the tool in contact with the heated bed or plate, and attached to the said shell A, substantially as and for the purposes described.
